| The spread of major diseases of molluscs around the world and the increase of transfers need the development of adapted prophylactic strategies and the increase of research in epidemiology, immunology and genetics. The prophylactic strategies must be based on common laws with the establishment of a list of declarable pathogens, with basic sampling rules (sample size, frequency, definition of geographical areas) and with reglementation of the internal transfers. Moreover, specific adapted diagnosis should be developed to increase the sanitary control performance (e.g. ELISA test, DNA probe, cell culture). In the case of an infectious disease the epidemiology studies should be concerned, the relationship between the culture techniques and the disease, the... |

| Bonamia ostreae, an intrahemocytic protozoan parasite infecting the oyster Ostrea edulis, is responsible for an endemic disease affecting all intensive breeding areas of European countries. Epidemiological studies showed variable prevalences, 43% in Galicia (Spain), from 6% to 32% in France and 45% in the most important area of Ireland. The impact of oyster transfers, handlings, high densities have been implicated in the disease development but environmental stressors could be more involved than zootechnical methods. The effect of water temperature, salinity and tidal exposure were particulary examined to assess stress induced changes and determine physiological, biochemical and immunological state indices of oyster populations, which will contribute to... |

| After a general presentation of the Thau lagoon together with its geographic location, socio-economic activities linked to shellfish culture and fishing, this paper investigates the health conditions of the shellfish harvesting areas. I he influence of heavy rainfall following a prolonged drought period is underlined as a determining factor of the momentary bacterial pollution in the harvesting areas, leading to a suspension of sales based on analyses relying solely on the detection of faecal coliforms. As of 1989, bacteriological monitoring was reorganized in the form of a data collection network taking into consideration environmental assessments of water quality as well as shellfish hygiene in order to protect consumer health. Its extension to the... |

| As part of the National Animal Health Monitoring System (NAHMS ), USDA:APHIS:Veterinary Services conducted a national study of beef production, the Beef Cow/Calf Health and Productivity Audit (CHAPA). This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. Data for Part 1: Beef Cow/Calf Herd Management Practices in the United States, were collected from beef producers September 29 through October 9, 1992. The National Agricultural Statistics Service (NASS) collaborated with VS to select a statistically designed producer sample that represented all U.S. cow/calf operations in the 48 continental United States. Eighty-one percent of operations had commercial cattle... |

This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. The National Agricultural Statistics Service (NASS) collaborated with USDA:APHIS:VS to select a producer sample that was statistically designed to provide inferences about the nation's cow/calf population. Data for Part IV: Beef Cow/Calf Breeding Management were collected by federal and state veterinary officers (VMO's) in 18 of the largest cow/calf producing states between July 1 and July 30, 1993. These 18 states... |

This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. Data for Part III: Beef Cow/Calf Health & Health Management were collected by federal and state veterinary officers (VMO's) in 18 of the largest cow/calf producing states between January 4 and February 28, 1993. These 18 states represented 70 percent of the U.S. beef cow inventory. Participating producers had five or more beef cows or beef replacement heifers and fifty percent or more of their 1992 calf crop... |
